(ID) Hidrologi suatu Daerah Aliran Sungai (DAS) rumit untuk diprediksi karena kekurangan data dan membutuhkan biaya yang mahal. Pada penelitian ini mengambil lokasi di sub DAS Rokan Hulu stasiun Pasir Pengaraian yang hampir setiap tahun terjadi banjir. Perencanaan dan pengolahan sumber daya air di suatu wilayah daerah aliran sungai sangat penting, maka dari itu perlunya mengetahui karakteristik suatu DAS. Perencanaan dan pengolaan sumber daya air memerlukan data debit aliran yang lengkap. Pada sub DAS ini data hujan, data debit dan data klimatologi menggunakan periode data sepuluh tahun yaitu dari tahun 2008-2017. Pemodelan hidrologi dilakukan pendekatan dengan beberapa metode, salah satunya metode soil moisture accounting di program HEC-HMS yang mana metode tersebut mensimulasikan suatu pergerakan air pada vegetasi, permukaan tanah dan di bawah permukaan tanah. Penyusunan periode kalibrasi dan verifikasi disusun dalam sembilan skema yang diharapkan mampu menghasilkan hasil yang paling optimal. Sembilan skema untuk Kalibrasi dan Verifikasi ini menggunakan metode objective function yaitu percent error in discharge volume. Skema yang paling optimal adalah skema VII (7 tahun kalibrasi 3 tahun Verifikasi), dengan nilai verifikasi 10,1%”Baik” dan Kalibrasi 0,0% “Sangat Baik”.

Information about low flow and water availability is one of the important factors in the management of water resources. The Rokan River Basin as one of the water resources in Riau Province is very important to know the condition of its water availability. One conceptual hydrological model for low flow analysis is the Tank Model developed by Sugawara. Data input needed in this research is daily rainfall data at Pasar Tangun Station, climatology data at Rambah Utama station and discharge data at AWLR Pasir Pengaraian. Model parameter search in the calibration stage is by trial and error. Using a 90% confidence interval a range of parameter values for the tank model is obtained, which is special for production store are surface flow 150.81 mm ≤ H1 ≤ 204.75 mm, intermediate flow 156.74 mm ≤ H2 ≤ 194.37 mm, sub base flow 141.24 mm ≤ H3 ≤ 176, 54 mm and base flow 139.43 mm ≤ H4 ≤ 176.12 mm.

This study was conducted to analyze the salinity of shallow well water so as to get an overview of the distribution of groundwater salinity at the research location. The research location is in the Selatpanjang City area, precisely in the Tebing Tinggi District and part of the Tebing Tinggi Barat District, Meranti Islands Regency. The research site is surrounded by the sea and rivers. Many people in the research location live in coastal areas. In coastal areas or near bodies of water, tidal water can enter up to the ground level and even onto roads. This situation makes people think that their groundwater is polluted due to tidal water entering the mainland. This research can provide information to the government and the community at the research site regarding the distribution of groundwater salinity that has occurred. The data analysis used is the interpolation method by creating a mapping using the ArcGIS application. Data analysis can be done after getting the data from the salinity measurement in the field. The water quality test parameters reviewed in this study were the salinity value of shallow wells water measured with a refractometer and marked the coordinates of the sample using the Avenza Maps application. In this study, 57 shallow wells were taken randomly. The results of field measurements show that based on salt concentration, shallow well water is classified as dubious and dangerous.

Metode penetapan seri data yang dipilih untuk analisis frekuensi akan sangat mempengaruhi besaran hujan rancangan. Mengingat data hujan pada DPS yang ada di Provinsi Riau khususnya DPS Siak cukup terbatas, menimbulkan kebutuhan untuk melakukan kajian pendekatan dalam memilih metode penetapan seri data agar analisis yang dihasilkan mempunyai keandalan yang baik. Melihat kasus ini, dibutuhkan suatu kajian tentang cara pendekatan dalam penentuan metode penetapan seri data yang dapat direkomendasikan dengan menentukan besarnya persentase perbedaan (penyimpangan) hujan rancangan dari kedua cara penetapan seri data yaitu Maximum Annual Series dan Partial Series. Hal ini nantinya akan berpengaruh pada penentuan berapa kali batasan maksimum perpanjangan data partial series yang dapat disarankan yang memberikan persentase perbedaan terkecil atau dapat diterima untuk keakuratan hasil analisa frekuensi. Perhitungan dan perbandingan hujan rancangan dari dua metode seri data tersebut dilakukan dengan bantuan program komputer dengan menggunakan bahasa Borland Delphi versi6.0. Program komputer yang dinamakan ADRP (Analysis of Design Rainfall Programme). Hasil perhitungan analisis variasi perpanjangan data menunjukkan semakin data PS diperpanjang menuju panjang data MAS, akan cenderung semakin besar atau meningkat perbedaannya terhadap data MAS pada kala ulang 2, 5, 10 dan 25 tahun dan nilai hujan rancangan juga semakin meningkat seiring peningkatan kala ulangnya yaitu hanya dari kala ulang 2, 5, 10 dan 25 tahun. Namun, pada kala ulang 50 dan 100 tahun tidak menunjukkan kecenderungan persentase perbedaan meningkat baik seiring perpanjangan data maupun seiring peningkatan kala ulangnya. Dari variasi perpanjangan data, batasan maksimum perpanjangan data partial series adalah dua kali data tersebut.

The forest fires that occurred in 2015 were very severe in the past 20 years. The forest fires caused a haze disaster for several months. The depth of groundwater plays an important role as a key in determining the risk of a fire occurring on peatlands. The purpose of this study is to create a hydrological model to predict the depth of the groundwater surface as a parameter for potential fires on peatlands using regression analysis. The location of the research is the village of Sungai Tohor. The data used for modeling are rainfall data and groundwater depth data that have been recorded historically on peatlands by installing SESAME at the research location and obtained data through the website address web.sesame-system.com. Regression analysis was performed using five data length scenarios, namely 1 month, 3 months, 6 months, 9 months, and 12 months to determine the period that could represent the hydrological conditions in the field. The results showed that the regression analysis with data lengths of 1 month, 3 months, 6 months, and 12 months gave the best prediction results for groundwater levels with strong correlation coefficient values of 0.80, 0.93, 0.89 and 0.94. Meanwhile, groundwater level prediction using regression analysis with 6 months length of data gives results with a moderate correlation value of 0.56.Key words: correlation value, groundwater level, peatlands, regression analysis.
